Facebook celebrated its 11th birthday last February, and like the nephew you rarely see, it's probably not the same youngster you remember. If your credit union is not on Facebook – or if you haven't revisited your Facebook strategy in a few years – here are ten new reasons to pump up your game.

1. Facebook is fast becoming a business channel. More than 30 million businesses now have a Facebook fan page, and the recent addition of a 'buy' button will accelerate its goal of becoming a global super-mall. Last year, sales exceeded $1 billion. Its treasure trove of personal data makes marketers salivate and is one reason why Target and Shutterfly recently opened sites.

2. Teenagers are jumping off, but the older crowd is jumping in. Between 2011 and 2014, Facebook saw a 25% drop in teens ages 13-17, while usage from the 35-54 crowd rose by 41%. Those over 55 jumped even higher to 80%. For the first time, more than half of all online adults ages 65 and older (56%) use Facebook. This is not your kid's Facebook.
